Notes: I can't be certain from these photos whether the golden brown colouration runs from shoulder to shoulder - it doesn't look like it does from the second photo but I can't be sure, therefore could be yellow-necked mouse too.

The flash may have made him more golden brown coloured than he was as it looked a dull brown out of the trap if thats any help.I checked for yellow neck marking when he was in the trap and didnt see any

Well, they are by far and away the most common mouse species in the UK and they seem to like live traps so they're recorded a lot too. Unlike field voles which are even more numerous but I assume don't like traps! - it's usually bank voles that turn up the most in traps even though they are actually a lot less common (about 1/3 as many I think) as field voles.
